YLiquids by Ultra-Violet Rays, of which the following is a full, clear, and exact description.

rlhe invention which constitutes the subject matter of this application relates to devices for the union of the lamp boxes and electrical accessories used in the sterilization of liquids, so that they form one part ont the sterilization chamber or else are suitably secured to the Wall of the sterilization tank.

In the, various' modifications .described hereinafter, the lamp chamber 1s So arran ed that in case of a break ot the protecting quartz tube the Water will not come in contact with the electric accessories. lin case the lamp box is hermetically closed, there must be provided a Siphon, sealed wlth a proper fluid, or equivalent means, to Iallow the escape of the water from the lamp chamber. v

.In the drawings, Figure 1 illustrates a part of a cross section of a sterilization tank or conduit and a cross sectional View ofthe accessory box secured thereto. Fig. .2 1s a central longitudinal section of the device shown in Fig. 1. Fig. 3. is a front view'otl the accessory box with the door partly broken away to show the inter1or construction, the bottom being where the hinges are.

Fig.6 illustrates another. form similar to the form shown in' Fig. 4, especially adapted for a vertical alternating current lamp. Fig. 7 lis aside view of the form shown in Fig. 6. Fig. l8

-side the sterilizng tank. Fig. 11 is a cenlib tral vertical section taken at right angles to the section shown-in Fig. 10. Fig. 12 illustrates the `preferred way of connecting the quartz tube to the accessory box. Fig. 13 illustrates an alternative method of connecting the quartz container to the accessory box. Fig. 14 is still another method of coniecting the quartz container to the accessory 1n all ot' the views the character A designates what l prefer to call, for the sake o1 convenience, the accessory box, while the character B designates a tank, trough or other container or conduit through' which the liquid is caused to How past a suitable source of ultra-violet rays for the purpose of being sterilized.

Referring to Figs. 1 to 3 inclusive, the character 11 designates a member, preferably of rectangular shape, to which the tube 14 and accessory box A may be secured. This securing means `is provided particularly when the tank or conduit B is made of concrete, and for securing the same in the concrete to withstand the pressure existing lin the tank l employ lugs or equivalent means 12. The member 11 is provided on the lnner side with a circular opening. 13

'to receive the quartz tube 14, into which the' ultra-violet ray lamp 15 may be projected. The outer'side of the member 10 is provided with a plurality of flanges 16 and corresponding flanges 1'? are provided on the lamp box 18 of the accessory box A, and by means. of lbolts 19 passing through 'these flanges, the accessory box may be securely fastened to the wall of the sterilizing tank or conduit. Between the resistance box 20 and the lamp box isv a partition, the central portion 21 of which is removable, but may be hermetically or otherwise sealed to the other portion 22 so as to exclude liquid from the resistancel box in case the quartz tube breaks, which not infrequently occurs. On the upper side of the lamp box, l provide a `mica window 23, suitably connected in position, and either transparent or translucent, or both, so as'to `ascertain visibly whether or not the lamp is in operation. rlhe front of the accessory box is provided with resistance boxes, and with vthe latter is employed any Well known resistance means indicated at 25. ,'lhe portion 220i the partition vis provided at the upper Side thereof-With a plurality of perforations to receive the leads 26 .and 27 from the 'resistance box,` and these leads are connected, of co'urse to the electrodes 28 and 29. "The lamp chamber is provided with suitable guides :74 whereby the lam-pl support 75 andlamp 15 nay be properly moved into and out of operative position without danger of breaking the said lamp or the quartz tube 14 in which said lamp is contained. p

In Figs. 4 and 5 I lllustrate a sllghtly modified form of the device, which contams a rheostat chamber 30, a lamp chamber 31, and an oil chamber 32, for high tension accessories with perforations 33 and 34, re-

spectively, in the partitions 35 and 36. TheI accessory box in this case is secured directly to the outersurface'of the sterilizing unit, by tight joint to prevent leakage. The o1l chamber 32 is provided with a removable closure 37. It may be remarked that in 'case the quartz tube should break, some means must be provided to drain the water from the lamp box and to do this I employ a trap 40, and while the same may be desirable in all the constructions illustrated, I only show it in Figs. 5 and 6.

Figs. 6 and 7 illustratev a form especlally adapted for an alternating current lamp, and in which the lamp, is vertically arranged. This form comprises the two chambers 41 and 42 between which is a removable partition 43, provided with one or ,more perforations therein for the conducting wires and an oil chamber` 44 located above the aforesaid chambers.

In Fig. 8 I show an arrangement in 'which the lamp is placed in a depending or hanging quartz tube; that is to say the accessory '-box is located above the sterilizing tank or the interior of the sterilizing erably in a depression 54 in lower end of the lamp chamber.

conduit. Two or more chambers 45 and 46 are employed, which have, preferably, a common closure 47. j

In Fig. 9 the Vnumeral 48 designates a lamp chamber preferably cylindrical in shape and to which the usual vapor lamp is located. In one `side of' this box there is located a perforation 49 for the leads.

Preferably on the opposite sides of the lamp chamber stitute a slot and screw connection between the lamp chamber and the sterilizing tank.

InFigs. 10 and 11 nates a lamp chamber which is locatedupon ploy a baiiie 56 having a central restricted` quartz tube is con-y nected and in which the .flanges 50'are provided, the slots' 51 of whlch, and the thumb-screws 52, con-v the numeral 53 desig-l of the Ato confine the gasket.- In

l*annular ange 69 opening 57 through which the liquid is forced to pass, whereby all the molecules are subjected to the ultra-violets rays emitted from the lamp. This baiie is employed 1n all the modifications villustrated for a further purpose, to wit, to cause a thorough agitation of the liquid Ias 1t flows by the source of rays.

In Fig. 12 I show the preferred method of connectin the quartztube 14 to the ac- ',5 cessory box Secured directly to the latter is an annular member 58, the internal diameter' of which is slightlygreater than the external diameter of the quartz tube 14. This member in cross section is in the form of a T, .the crossl being indicated at 59 and 60, `and the'leg portions at 61, the latter having a pluralityof screw threaded holes 62 therein, which are adapted to receive the screw-threaded securing members 63, the latter in turn adapted to hold the annular member 64 in position. This annular member is also T-shapedin cross section, the leg ofthe T being indicated at 65 and the cross portions at 66 and 67. The leg is beveled .at the upper" portion, as shown, and tele- 'scopes with theannular leg portion 61 of member58. Located between the beveled portions of the leg 65 and the portion 60 of the member 58 is an annular gasket 68. 95

By the act of screwingthe bolts 63, the gasket is compressed and causes the same to become smaller in diameter, as will be obvious, and thereby firmly engages the quartz` tube. This engagement is suiiicientlto hold 10o the quartz tube in placewhere there is either little or no pressure in the sterilizing tank. When there is some pressure, however, in the tank, the quartz tube cannot be gripped suiiiciently to withstand this pressure, owing to its extremedelicacy. Furthermore, asa matter of economicaloperation, .this liabil- .ity to breakage must be reduced to a minimum, onl account of the expensiveness of the quartz tube. Todo this the annular iange llo 67 is located in the path of the end of the quartz tube and upon which the latter normally rests to withstand the pressure existing in the tank. The. clamping ring 58 servesto furnish a replaceable element in case of accident.

' In Fig. 13 I illustrate a modied formyarrangement shown in Fig. 12. In this case .the member 58 is entirely omitted, andthe member 64 connected directly 120 to the box A. In Fig. 12 the leg 61 serves F ig. 13 this functlon 1s performed by the shoulder 68 and, of course, the part 69, of the tank wall perfunction as the flange 60 125 oli Iigggylvw-` Fig. 14 illustrates a still further modification ofthe connectionbetween the quartz Between the and clamping ring 76 is a. 130
